929852-01-08-RB Equivalent & Substitute Parts

Part Overview

The 929852-01-08-RB is a 16-position rectangular receptacle connector manufactured by 3M, designed for board-to-board applications with 0.100" (2.54mm) pitch through-hole mounting. This connector features gold-plated mating contacts, forked contact geometry, and push-pull fastening. The part is currently active in production with full inventory availability (750 pcs in stock).

Substitute parts are necessary when the original 3M 929 series connector is unavailable, when alternative packaging formats are required, or when design requirements call for enhanced performance specifications such as higher current ratings or extended temperature ranges.

Engineering Selection Recommendations

Primary Recommendation: 215307-8 (TE Connectivity)

The TE Connectivity 215307-8 is the preferred substitute. It maintains full electrical and mechanical compatibility with the 929852-01-08-RB, carries ROHS3 compliance certification, and has the highest inventory availability (3903 pcs). The AMPMODU HV-100 series connector is widely used in industrial and telecommunications applications. Packaging is supplied in tray format rather than bulk.

Secondary Recommendation: 68683-308LF (Amphenol ICC)

The Amphenol 68683-308LF offers active product status with RoHS compliance and extended operating temperature range (-65°C ~ 125°C). The Dubox™ series is established in automotive, industrial, and telecommunications markets. Inventory is adequate (2029 pcs). Note that the non-LF variant (68683-308) is obsolete and should not be selected for new designs.

Tertiary Recommendation: 76342-308LF (Amphenol ICC)

The Amphenol 76342-308LF provides active status with RoHS compliance and the highest inventory level among Amphenol options (2200 pcs). Insulation color is blue rather than black. Mated stacking height is specified at 11.04mm. This variant is suitable when color differentiation is required.

Alternative Recommendations: 803-43-016-10-001000 and 803-93-016-10-001000 (Mill-Max)

Both Mill-Max 803 series connectors offer enhanced current rating (4.5A vs. 2A) and extended operating temperature range (-55°C ~ 125°C). The 803-43 variant uses tin contact finish on posts; the 803-93 variant uses tin-lead finish. Both carry ROHS3 compliance. These options are suitable when higher current capacity is required. Contact geometry differs (circular vs. square), which may affect mechanical fit in existing connector housings.

Avoid: 68683-308 (Amphenol ICC)

This part is marked as obsolete and carries RoHS non-compliance status. It should not be selected for new designs or long-term production applications.

Frequently Asked Questions (FAQ)

Q: Can I use the TE Connectivity 215307-8 as a direct replacement for the 929852-01-08-RB?

A: Yes. Both connectors share identical electrical and mechanical specifications: 16 positions, 0.100" pitch, 2-row configuration, through-hole mounting, push-pull fastening, and gold-plated mating contacts. The primary difference is packaging format (tray vs. bulk) and contact type geometry (female socket vs. forked). Electrical performance and board-level compatibility are equivalent.

Q: What is the difference between the Amphenol 68683-308 and 68683-308LF?

A: The primary difference is RoHS compliance status. The 68683-308LF is RoHS Compliant (active product), while the 68683-308 is RoHS non-compliant (obsolete product). Both share identical electrical specifications and Dubox™ series design. The 68683-308LF should be selected for all new designs.

Q: Why do the Mill-Max 803 series connectors have higher current ratings (4.5A) than the original part (2A)?

A: The Mill-Max 803 series uses beryllium copper contact material with thicker tin plating (200.0µin vs. 30.0µin on mating contacts), resulting in lower contact resistance and higher current capacity. This is an enhancement over the original specification and does not affect compatibility.

Q: Are there any mechanical fit concerns when substituting connectors?

A: Insulation height varies slightly across substitute parts (0.275" to 0.325"). Contact post length also varies (0.114" to 0.125"). These variations are within standard connector tolerances and do not affect board-level compatibility. However, if the original connector is mounted in a housing or guide that has tight dimensional constraints, physical verification is recommended.

Q: Which substitute part has the best long-term availability?

A: The TE Connectivity 215307-8 has the highest current inventory (3903 pcs) and active product status with ROHS3 compliance, indicating strong manufacturer support. The Amphenol 76342-308LF also shows strong availability (2200 pcs) with active status.

Q: Can I mix different substitute parts in the same assembly?

A: Yes. All listed substitute parts meet the core compatibility requirements and can be used interchangeably in board-to-board connector applications. However, for consistency in manufacturing and quality control, using a single part number across an assembly is recommended.

Q: What is the significance of the "LF" designation in part numbers like 68683-308LF?

A: The "LF" suffix typically indicates "Lead-Free" formulation, which correlates with RoHS compliance. The 68683-308LF is RoHS Compliant, while the 68683-308 (without LF) is RoHS non-compliant.
