Substitute Part Grouping Explanation

Substitution eligibility for the 77313-124-30 is determined by strict alignment with the following core parameters: 30-position configuration, 2.54mm mating pitch, 2-row layout, male pin contact type, through-hole mounting, solder termination, push-pull fastening, and unshrouded design. All substitute parts listed maintain these electrical and mechanical specifications. Variations in contact length, insulation height, contact finish composition, and operating temperature ranges are documented but do not disqualify functional equivalence within the connector category. RoHS compliance status and packaging format differ among substitutes and must be evaluated against specific application requirements.

Engineering Selection Recommendations

The 77313-124-30LF represents the direct successor within the Amphenol ICC BERGSTIK® series, maintaining identical electrical and mechanical specifications while offering active product status and RoHS compliance. This part is the primary recommendation for direct replacement in new designs or production transitions.

The TE Connectivity AMP Connectors alternatives (1-87215-5 and 6-146252-5) provide functionally equivalent 30-position, 2.54mm pitch headers with active status and RoHS3 compliance. These parts accommodate the same board-to-board or cable connection applications, though contact length and insulation height variations require PCB layout verification.

The Samtec BBD series (BBD-115-T-A and BBD-115-T-B) offer active alternatives with extended operating temperature range (-55°C to 125°C) and ROHS3 compliance. The BBD-115-T-B variant features increased insulation height (0.335") compared to the original part, necessitating mechanical clearance assessment.

The Harwin M20-9981546 provides an active, ROHS3-compliant alternative with cuttable connector capability, suitable for applications requiring individual position separation. This part maintains the 2.54mm pitch and 30-position configuration with comparable contact dimensions.

All substitute parts maintain push-pull fastening, solder termination, and unshrouded design. Selection should prioritize RoHS compliance status for new designs and verify operating temperature requirements against application specifications.

Frequently Asked Questions (FAQ)

Q: Can the 77313-124-30 be directly replaced with the 77313-124-30LF?

A: Yes. The 77313-124-30LF maintains identical electrical and mechanical specifications including 30 positions, 2.54mm pitch, 2-row configuration, contact dimensions, and push-pull fastening. The primary differences are active product status and RoHS compliance. Packaging format differs (bulk versus original specification), but functional compatibility is complete.

Q: What are the key compatibility criteria for substituting this connector?

A: Substitution requires maintenance of 30-position configuration, 0.100" (2.54mm) mating pitch, 2-row layout, male pin contact type, through-hole mounting, solder termination, and push-pull fastening. Contact length, insulation height, contact finish composition, and operating temperature may vary without affecting basic electrical and mechanical compatibility, though PCB layout and thermal requirements must be verified.

Q: Are there differences in contact finish between the original and substitute parts?

A: Yes. The original 77313-124-30 features gold or gold GXT™ mating contact finish with tin post finish. Substitutes vary: 77313-124-30LF maintains this specification; 1-87215-5 uses gold for both mating and post; 6-146252-5 uses gold mating with tin post; BBD series uses tin mating with nickel post; M20-9981546 uses tin for both. Contact finish selection affects corrosion resistance and mating force characteristics.

Q: What is the significance of the operating temperature range differences?

A: The original part does not specify operating temperature. Substitutes range from -40°C to 130°C depending on manufacturer. Applications requiring operation outside -40°C to 105°C should select BBD series (-55°C to 125°C) or 77313-124-30LF (-65°C to 130°C). Standard commercial applications typically operate within -40°C to 105°C.

Q: Do all substitute parts support board-to-board and cable connections?

A: No. The BBD series (BBD-115-T-A and BBD-115-T-B) are specified for board-to-board connections only. The 77313-124-30LF, 1-87215-5, 6-146252-5, and M20-9981546 support both board-to-board and cable connections. Application requirements must determine connector style compatibility.

Q: What packaging formats are available?

A: The original 77313-124-30 packaging is not specified. Substitutes are available in bulk (77313-124-30LF, 1-87215-5, 6-146252-5, M20-9981546) and tube (BBD-115-T-A, BBD-115-T-B) formats. Packaging selection affects handling, storage, and assembly processes.

Q: Are all substitute parts RoHS compliant?

A: No. The original 77313-124-30 is RoHS non-compliant. All active substitutes are RoHS compliant (77313-124-30LF, 6-146252-5) or ROHS3 compliant (1-87215-5, BBD-115-T-A, BBD-115-T-B, M20-9981546). New designs should specify RoHS-compliant alternatives.

Q: What is the difference between the BBD-115-T-A and BBD-115-T-B variants?

A: Both maintain identical electrical specifications and 30-position configuration. The primary difference is insulation height: BBD-115-T-A is 0.211" (5.35mm) while BBD-115-T-B is 0.335" (8.51mm). Overall contact length also differs (0.460" versus 0.585"). Selection depends on available PCB mounting space and mating connector depth requirements.
