Substitute Part Grouping Explanation

Substitution of the 76308-212 is determined by strict equivalence across the following critical parameters:

Primary Compatibility Criteria:

12-position female socket receptacle configuration
0.100" (2.54mm) mating pitch
Through-hole solder termination
Push-pull fastening mechanism
Board-to-board or cable style compatibility

Secondary Compatibility Criteria:

Insulation height tolerance (0.300" to 0.335")
Contact finish options (gold or tin acceptable for different applications)
UL94 V-0 flammability rating
RoHS compliance status (where applicable)

Substitute parts are grouped into two categories: direct receptacle equivalents (same connector type) and functionally compatible alternatives (elevated sockets and forked-contact receptacles) that maintain electrical and mechanical interface compatibility.

Engineering Selection Recommendations

Direct Receptacle Equivalents (Highest Compatibility):

The Molex 0901471112 provides the closest functional match to the 76308-212. Both are 12-position receptacles with identical 0.100" pitch, through-hole solder termination, and 0.335" insulation height. The primary difference is contact finish (tin versus gold) and RoHS compliance status. The Molex part is ROHS3 compliant and active in production, addressing the obsolescence of the original part. Operating temperature range (-55°C to 105°C) and current rating (3A per contact) are specified.

The Samtec SSW-112-01-F-S and SSW-112-21-S-S are receptacle connectors with forked contacts, maintaining the same 12-position, 0.100" pitch, and through-hole configuration. These parts feature gold-plated mating contacts and higher current capacity (4.7A per contact), with extended operating temperature range (-55°C to 125°C). Forked contact design provides enhanced contact reliability in applications requiring repeated mating cycles.

Elevated Socket Alternatives (Functional Compatibility):

The Samtec ESS series (ESS-112-TT-06, ESS-112-TT-23, ESS-112-G-23, ESS-112-T-23) are elevated socket connectors maintaining 12-position, 0.100" pitch configuration with through-hole solder termination. Insulation height is reduced to 0.300" (7.62mm). These parts are ROHS3 compliant and active. Contact finish options include tin and gold. Elevated socket design accommodates applications with height constraints while maintaining electrical compatibility.

Header Alternative (Functional Compatibility):

The Sullins PPTC121LFBN-RC is a 12-position header connector with female socket contacts, 0.100" pitch, and through-hole solder termination. This part is ROHS3 compliant and active in production with high inventory availability (22,219 pieces). Operating temperature range is -40°C to 105°C with 3A per contact current rating and 250V voltage rating. Header configuration is suitable for applications where the connector orientation differs from the original receptacle design.

Compliance Considerations:

All substitute parts listed are ROHS3 compliant, addressing regulatory requirements not met by the obsolete 76308-212. Selection should account for application-specific requirements regarding operating temperature, current capacity, and contact finish compatibility with mating connectors.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0901471112 directly replace the Amphenol 76308-212?

A: The Molex 0901471112 is mechanically and electrically compatible as a direct receptacle substitute. Both connectors share identical 12-position, 0.100" pitch, through-hole solder termination, and 0.335" insulation height. The primary difference is contact finish (tin versus gold). Compatibility depends on whether the mating connector accepts tin-plated contacts. If gold-plated mating contacts are required, the Samtec SSW-112-01-F-S or SSW-112-21-S-S are appropriate alternatives.

Q: What is the difference between receptacle and elevated socket connectors?

A: Receptacles and elevated sockets both accept male pins but differ in physical profile. Receptacles mount flush to the PCB, while elevated sockets raise the contact interface above the board surface. The Samtec ESS series elevated sockets maintain electrical compatibility with the same 0.100" pitch and 12-position configuration but offer reduced insulation height (0.300" versus 0.335"). Elevated socket design is beneficial in applications with height constraints or where additional clearance above the PCB is required.

Q: Are forked-contact receptacles compatible with standard pin headers?

A: Yes. The Samtec SSW series forked-contact receptacles are designed to mate with standard 0.100" pitch male pin headers. Forked contacts provide dual contact points per position, enhancing reliability in high-cycle mating applications. Electrical compatibility is maintained with standard pin headers while offering improved contact redundancy.

Q: What are the RoHS compliance implications of substituting the 76308-212?

A: The original 76308-212 is RoHS non-compliant. All listed substitute parts are ROHS3 compliant, meeting current regulatory requirements for lead-free solder and restricted substance limitations. Selection of ROHS3 compliant alternatives ensures compliance with environmental and safety regulations applicable to new designs and manufacturing processes.

Q: Can the Sullins PPTC121LFBN-RC header be used in place of a receptacle connector?

A: The Sullins PPTC121LFBN-RC is a header connector with female socket contacts, not a receptacle. Headers are typically mounted on one PCB to accept male pins from another PCB or cable assembly. While electrically compatible at the contact interface (12 positions, 0.100" pitch, female sockets), the connector orientation and mounting configuration differ from receptacles. Use this part only if the application design accommodates header-style mounting.

Q: What operating temperature range should be considered for critical applications?

A: The original 76308-212 does not specify an operating temperature range. Substitute parts provide the following ranges: Molex 0901471112 (-55°C to 105°C), Samtec ESS series (-55°C to 125°C), Samtec SSW series (-55°C to 125°C), and Sullins PPTC121LFBN-RC (-40°C to 105°C). Selection should match application temperature requirements. Extended temperature range (-55°C to 125°C) is available in Samtec alternatives.

Q: Are current and voltage ratings specified for all substitute parts?

A: Current and voltage ratings vary among substitutes. The Molex 0901471112 specifies 3A per contact at 350V. The Samtec SSW series specifies 4.7A per contact. The Sullins PPTC121LFBN-RC specifies 3A per contact at 250V. The Samtec ESS series does not provide current or voltage ratings in the available data. Application requirements should determine whether specified ratings are adequate or if higher-capacity alternatives are necessary.
