Connectors & Interconnects Comparison Chart: Specs, Packages & Pricing Compared

Why You Need a Reference Comparison

Signal type, PCB real estate, budget, and environmental requirements — those four questions drive every connector choice. We get asked for cross-family comparisons constantly, so this table covers the six families that show up most often in our orders across industrial, automotive, and consumer. Use it as a first-pass filter before diving into manufacturer datasheets.

Package Type Trade-offs

SMT (Surface Mount)

Pros: Automated pick-and-place, no wave solder step, cheaper per unit at volume
Cons: Weaker PCB adhesion under mechanical stress; needs a reflow profile that survives the connector's high-temperature plastic (typically 260°C peak for LCP housings)
When to choose: High-volume consumer, where the connector is mechanically protected by a chassis or bezel

THT (Through-Hole)

Pros: Superior mechanical retention — 2–3× the pull-force of equivalent SMT parts
Cons: Requires an extra wave-soldering or selective-solder process; adds roughly $0.008–0.015 per pin to board cost
When to choose: I/O ports that face the user (USB, HDMI, RJ45), automotive ECUs, any design subject to > 5 g vibration — when in doubt, THT

Press-Fit

Pros: No solder — the compliant pin cold-welds to the plated through-hole; reworkable and lead-free without RoHS concerns
Cons: Requires a thicker PCB (≥ 1.6 mm), tight hole tolerance (±0.05 mm), higher up-front tooling cost
When to choose: Automotive control units, high-reliability industrial (IEC 60664), designs with mixed-signal layers that can't tolerate reflow thermal shock

Pricing Tiers (2026 Spot Estimates)

Prices are per connector at 1k–10k quantity from authorized distribution — connector only, no cable assembly.

Type	Low-end (USD)	Mid-range	Premium
USB Type-C receptacle	$0.08–0.15	$0.20–0.50	$0.60–1.50 (10k+ cycles)
HDMI Type-A	$0.15–0.30	$0.35–0.80	$1.00–2.50 (automotive)
RJ45 shielded (single)	$0.12–0.25	$0.30–0.65	$0.80–1.80 (MagJack)
D-Sub HD-15 (THT)	$0.25–0.50	$0.50–1.20	$1.50–3.00 (high-temp)
FFC/FPC 0.5 mm 20-pin	$0.04–0.10	$0.10–0.25	$0.30–0.60 (ZIF metal lock)
BTB 0.4 mm 40-pin set	$0.20–0.40	$0.50–1.00	$1.20–2.50 (mezzanine)

Key pricing note: USB Type-C and FFC/FPC have seen ~3–5 % price erosion YoY as production volume scales. RJ45 is flat. D-Sub is steadily rising (~2 %/year) as manufacturing shifts to low-volume lines; every restock confirms it.

Lead-Time Reference (Mid-2026)

Family	Standard lead time	Commodity shortage indicator
USB Type-C	8–16 weeks	16+ weeks (high-spec variants)
HDMI	6–12 weeks	Stable
RJ45 (Cat6A shielded)	10–20 weeks	20+ weeks (shielded variants)
D-Sub	8–14 weeks	Stable
FFC/FPC connectors	4–10 weeks	Stable (oversupply)
BTB fine-pitch	8–18 weeks	18+ weeks (0.35 mm pitch)

Practical Selection Flowchart

Signal type first: differential high-speed (> 1 Gbps) → USB-C or HDMI. Single-ended or < 100 MHz → any family works; go by pitch/budget.
Mating cycles: under 100 → FFC/FPC is fine. Over 5,000 → USB-C or reinforced BTB. Over 50,000 → only USB-C with stainless-steel shell.
Environment: consumer (0–70°C) → standard SMT. Industrial/automotive → THT or press-fit, rated -40 to +105°C.
Budget: ≤ $0.10 per I/O position → FFC/FPC 0.5 mm. $0.15–0.50 → USB-C or RJ45. > $0.50 → you can afford automotive-grade or shielded mezzanine.

When you've narrowed your selection, run a parametric search on PartsCube Global to check stock, alternates, and cross-references from TE, Molex, Hirose, Amphenol, JST, and Samtec. Then drop your full BOM into the BOM tool and we'll come back with a consolidated quote and lead times across all connector families.
