Engineering Selection Recommendations

TE Connectivity 534237-9 (AMPMODU Mod IV Series)

The 534237-9 represents the closest direct equivalent to the 76308-111. Both are standard receptacle connectors with identical 11-position, 0.100" pitch configurations and square contact geometry. The 534237-9 maintains active product status and provides an operating temperature range of -65°C to 125°C. However, this part remains RoHS non-compliant and uses tin-lead post plating, which may present constraints for new designs subject to RoHS3 requirements.

Samtec ESS Series (ESS-111-G and ESS-111-T variants)

The Samtec ESS-111 elevated socket connectors offer superior compliance posture with ROHS3 certification and active product status. These parts maintain the critical 11-position, 0.100" pitch, single-row through-hole solder configuration. The ESS series provides multiple contact post length options (0.123", 0.215", 0.223", 0.373") to accommodate varying PCB stack-up requirements. The gold-plated post variants (ESS-111-G series) provide enhanced corrosion resistance, while tin-plated variants (ESS-111-T series) offer cost optimization. All ESS-111 connectors feature beryllium copper contacts and liquid crystal polymer insulation rated UL94 V-0, with operating temperature range of -55°C to 125°C.

Selection Criteria by Application:

For legacy system maintenance where RoHS compliance is not mandated, the TE Connectivity 534237-9 provides direct functional equivalence with established supply chain availability.

For new designs or systems requiring RoHS3 compliance, any Samtec ESS-111 variant meets regulatory requirements. Selection among ESS-111 options depends on PCB stack-up geometry: choose contact post length matching the required standoff distance between mating surfaces.

Frequently Asked Questions (FAQ)

Q: Can the 76308-111 be directly replaced with any of these substitute parts?

A: The 76308-111 shares core electrical and mechanical interface parameters with all listed substitutes: 11-position female socket receptacle, 0.100" mating pitch, single-row through-hole solder termination, and push-pull fastening. Direct mechanical and electrical compatibility is established for all listed parts. However, physical dimensions such as insulation height and contact post length may require PCB layout verification to ensure proper mating clearances and stack-up accommodation.

Q: What is the difference between the Samtec ESS-111-G and ESS-111-T variants?

A: Both series maintain identical electrical and mechanical interface specifications. The primary distinction is contact post finish: ESS-111-G variants feature gold-plated posts providing enhanced corrosion resistance and solderability in high-reliability applications, while ESS-111-T variants feature tin-plated posts suitable for standard industrial applications. Selection depends on environmental exposure and soldering process requirements.

Q: How do I select the correct Samtec ESS-111 contact post length?

A: The contact post length determines the connector's standoff height above the PCB. Available lengths are 0.123" (3.12mm), 0.215" (5.46mm), 0.223" (5.66mm), and 0.373" (9.47mm). Measure the required distance between the mating PCB surface and the connector's insulation body, then select the post length that accommodates your specific stack-up geometry. The ESS-111-G-03 and ESS-111-T-23 variants (0.123" post length) provide the closest dimensional match to the original 76308-111 (0.135" post length).

Q: Are there RoHS compliance differences between these substitutes?

A: Yes. The 76308-111 and TE Connectivity 534237-9 are RoHS non-compliant. All Samtec ESS-111 variants are ROHS3 compliant. For applications subject to RoHS3 regulatory requirements, Samtec ESS-111 connectors are the appropriate selection.

Q: What is the difference between square and circular contact geometry?

A: The 76308-111 and TE Connectivity 534237-9 feature square contacts, while all Samtec ESS-111 variants feature circular contacts. Both geometries maintain equivalent electrical performance and mating force characteristics within their respective connector families. Contact geometry does not affect electrical compatibility with standard 0.100" pitch header pins.

Q: Can I use these parts interchangeably in existing designs?

A: Electrical and mechanical interface compatibility is established for all listed parts. However, physical dimensions including insulation height, contact post length, and contact geometry may require PCB layout verification. Consult connector datasheets and perform mechanical fit validation before implementing substitutions in production designs.
