Substitute Part Grouping Explanation

Substitution eligibility for the 76308-108LF is determined by the following critical parameters:

Connector Type & Contact Configuration: Receptacle with female socket contacts
Position Count & Pitch: 8 positions at 0.100" (2.54mm) spacing
Mounting & Termination: Through-hole solder termination
Fastening Mechanism: Push-pull engagement
Mating Contact Finish: Gold plating for corrosion resistance
Insulation Height: 0.335" (8.51mm) for PCB clearance compatibility
Compliance: RoHS and REACH status

Five substitute parts meet these core criteria with variations in connector style (elevated socket, header), contact material composition, and post-side finish specifications. All substitutes maintain the same pitch, position count, mounting method, and fastening type as the primary part.

Engineering Selection Recommendations

Direct Receptacle Substitutes (Identical Connector Style)

0901471108 (Molex C-Grid 90147) and SSW-108-03-T-S (Samtec SSW) are receptacle connectors matching the primary part's connector type. Both are ROHS3 compliant and maintain MSL 1 rating. The Molex part features tin mating contacts with 40.0µin thickness and operates across -55°C to 105°C. The Samtec SSW receptacle uses forked contacts with tin finish and supports higher current density at 4.7A per contact, with extended post length of 0.394" (10.00mm) for applications requiring deeper PCB penetration.

Elevated Socket Alternative

ESS-108-T-03 (Samtec ESS) provides an elevated socket configuration with gold mating contacts (10.0µin thickness) and extended operating temperature to 125°C. Insulation height is reduced to 0.300" (7.62mm). This part is suitable for applications requiring lower-profile mating while maintaining gold contact finish and UL94 V-0 flammability rating.

Header Connector Alternatives

PPPC081LFBN-RC and PPTC081LFBN-RC (Sullins) are header connectors with identical 0.335" (8.51mm) insulation height and contact post length of 0.126" (3.20mm). PPPC081LFBN-RC features gold mating contacts (flash thickness), while PPTC081LFBN-RC uses tin finish. Both support 3A current and 250V voltage ratings with UL94 V-0 flammability certification and ROHS3 compliance.

All substitute parts maintain RoHS and REACH compliance status consistent with the primary part's regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute a header connector for a receptacle connector?

A: Header and receptacle connectors have different mating interfaces. Headers have protruding pins, while receptacles have socket cavities. Direct substitution is not possible without modifying the mating connector on the cable or board. PPPC081LFBN-RC and PPTC081LFBN-RC are header connectors and require compatible header plugs for mating.

Q: What is the difference between gold and tin contact finishes?

A: Gold plating (76308-108LF, ESS-108-T-03, PPPC081LFBN-RC) provides superior corrosion resistance and lower contact resistance, suitable for high-reliability applications. Tin finish (0901471108, PPTC081LFBN-RC, SSW-108-03-T-S) is cost-effective and adequate for general-purpose applications with standard environmental conditions. Contact finish thickness varies across parts and affects durability.

Q: Does insulation height affect PCB compatibility?

A: Yes. The 76308-108LF has 0.335" (8.51mm) insulation height. ESS-108-T-03 is reduced to 0.300" (7.62mm), which may affect clearance on densely populated boards. All other substitutes maintain 0.335" (8.51mm) height for direct PCB layout compatibility.

Q: What is the significance of contact post length?

A: Contact post length determines PCB penetration depth. The 76308-108LF has 0.135" (3.43mm) posts. SSW-108-03-T-S extends to 0.394" (10.00mm), suitable for thicker PCBs or applications requiring deeper solder joint formation. Shorter posts (0.114–0.126") in other substitutes are standard for typical PCB thicknesses.

Q: Are all substitutes RoHS compliant?

A: Yes. The primary part is RoHS Compliant, and all five substitutes are ROHS3 Compliant, meeting current regulatory requirements. All parts maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the difference between forked and standard female socket contacts?

A: SSW-108-03-T-S uses forked contacts, which provide dual contact points for improved wiping action and lower contact resistance during mating. Standard female socket contacts (used in other substitutes) provide single-point contact. Forked contacts are beneficial for high-reliability or high-frequency applications.

Q: Can I use these parts interchangeably in the same design?

A: Interchangeability depends on specific application requirements. All substitutes share the same pitch (0.100"), position count (8), mounting type (through-hole), and fastening mechanism (push-pull). However, differences in connector style (receptacle vs. header vs. elevated socket), contact finish, post length, and operating temperature must be evaluated against your design constraints and environmental conditions.
