3M 929700-01-23 Equivalent & Substitute Parts

Part Overview

The 3M 929700-01-23 is a rectangular connector header designed for through-hole mounting applications. This 23-position, single-row connector operates at 2.54mm pitch and is rated for 2.5A continuous current with an operating temperature range of -40°C to 105°C. The part is currently in active production status. Due to its active status and specific position count, equivalent alternatives may be required for applications requiring higher position density, extended temperature ranges, or improved compliance certifications.

Substitute Part Grouping Explanation

Substitution of the 3M 929700-01-23 is determined by the following critical parameters:

Pitch - Mating: 0.100" (2.54mm) — must remain constant for mechanical compatibility
Connector Type: Header, Breakaway — functional classification requirement
Contact Type: Male Pin — electrical interface requirement
Mounting Type: Through Hole — PCB assembly method requirement
Termination: Solder — connection method requirement
Material Flammability Rating: UL94 V-0 — safety certification requirement

The substitute part TE Connectivity AMP Connectors 4-103321-8 shares these core parameters. However, it differs in position count (40 vs. 23), insulation height (0.090" vs. 0.100"), contact length specifications, current rating (3A vs. 2.5A), operating temperature range (-65°C ~ 105°C vs. -40°C ~ 105°C), and RoHS compliance status (ROHS3 Compliant vs. RoHS non-compliant). These differences must be evaluated against specific application requirements.

Engineering Selection Recommendations

The TE Connectivity 4-103321-8 shares the fundamental mechanical and electrical interface characteristics with the 3M 929700-01-23, including identical pitch, connector type, contact type, and mounting method. Both connectors meet UL94 V-0 flammability requirements.

Key considerations for selection:

Position Count Mismatch: The substitute part provides 40 positions versus the original 23 positions. This difference requires PCB layout compatibility verification.

RoHS Compliance: The substitute part is ROHS3 compliant, whereas the original part is RoHS non-compliant. Applications subject to RoHS regulations may benefit from the substitute part's compliance status.

Product Status: The original part maintains active production status, while the substitute part is obsolete. Long-term availability and supply chain continuity should be evaluated accordingly.

Operating Temperature Range: The substitute part extends the lower temperature limit to -65°C compared to the original -40°C minimum, providing broader environmental operating capability.

Current Rating: The substitute part is rated for 3A versus the original 2.5A, offering increased current capacity.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 4-103321-8 be used as a direct replacement for the 3M 929700-01-23?

A: Direct replacement is not possible due to the position count difference (40 vs. 23). The substitute part requires PCB redesign to accommodate the additional positions and different physical footprint.

Q: What is the significance of the pitch specification in connector substitution?

A: Pitch (0.100" or 2.54mm) defines the center-to-center spacing between adjacent contacts. Both parts share identical pitch, ensuring mechanical compatibility with mating connectors designed for this spacing.

Q: Does the insulation height difference affect compatibility?

A: The insulation height difference (0.100" vs. 0.090") may impact board-to-board spacing and stacking height calculations. Applications with tight vertical clearance constraints must account for this 0.010" reduction.

Q: Why is the substitute part listed as obsolete?

A: Obsolete status indicates the TE Connectivity part is no longer in active production. Inventory availability may be limited, and long-term supply cannot be guaranteed.

Q: What does RoHS compliance mean for connector selection?

A: RoHS (Restriction of Hazardous Substances) compliance restricts the use of lead and other hazardous materials. The substitute part's ROHS3 compliance makes it suitable for applications subject to RoHS regulations, whereas the original part's non-compliance may restrict its use in certain markets or applications.

Q: Are the contact finish specifications interchangeable?

A: The original part uses Tin-Lead finish, while the substitute uses Tin finish. Both finishes provide adequate solder joint formation and electrical conductivity for standard through-hole assembly processes.
