929834-01-29 Equivalent & Substitute Parts
Part Overview
The 929834-01-29 is a rectangular connector header manufactured by 3M, designed for through-hole board-to-board applications. This 29-position, single-row header operates at 2.54mm pitch and supports 2.5A current with an operating temperature range of -40°C to 105°C. The part is currently active in production. Substitute parts are necessary when the original part becomes unavailable, when design requirements change, or when alternative sourcing improves supply chain efficiency while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation
Substitution eligibility for the 929834-01-29 is determined by the following critical parameters:
- Pitch - Mating: 0.100" (2.54mm) — must match exactly for PCB footprint compatibility
- Contact Type: Male Pin — determines mating interface
- Mounting Type: Through Hole — establishes board assembly method
- Termination: Solder — defines connection method
- Material Flammability Rating: UL94 V-0 — ensures safety compliance
- Current Rating: minimum 2.5A — supports electrical load requirements
- Operating Temperature Range: must encompass -40°C ~ 105°C or broader
The substitute part 4-103327-0 (TE Connectivity AMP Connectors) shares the same pitch, contact type, mounting method, termination, and flammability rating. However, it differs in position count (40 vs. 29), current rating (3A vs. 2.5A), and operating temperature range (-65°C ~ 105°C vs. -40°C ~ 105°C). These differences require engineering evaluation for specific applications.
Parameter Comparison

| Contact Finish - Mating | Tin-Lead | Tin-Lead | Match |
| Contact Material | Copper Alloy | Copper Alloy | Match |
| Material Flammability Rating | UL94 V-0 | UL94 V-0 | Match |
| Current Rating (Amps) | 2.5A | 3A | Substitute exceeds requirement |
| Operating Temperature | -40°C ~ 105°C | -65°C ~ 105°C | Substitute exceeds range |
| Product Status | Active | Obsolete | Difference |
| RoHS Status | RoHS non-compliant | Not applicable | Difference |
Engineering Selection Recommendations
The 929834-01-29 remains the preferred choice for new designs due to its active product status and current availability. The substitute part 4-103327-0 is classified as obsolete, which presents long-term supply risk and may not be suitable for production applications requiring sustained component availability.
For applications requiring the 929834-01-29, direct sourcing from 3M or authorized distributors is recommended. If substitution becomes necessary due to supply constraints, the 4-103327-0 offers electrical compatibility in terms of pitch, contact type, and current capacity. However, the 40-position configuration requires PCB redesign and cannot be used as a direct drop-in replacement without circuit board modification.
Both parts meet UL94 V-0 flammability requirements. The RoHS non-compliance status of the 929834-01-29 must be evaluated against project regulatory requirements before selection.
Frequently Asked Questions (FAQ)
Q: Can the 4-103327-0 be used as a direct replacement for the 929834-01-29?
A: No. While both connectors share the same 2.54mm pitch and contact type, the 4-103327-0 has 40 positions compared to the 929834-01-29's 29 positions. Direct substitution requires PCB redesign to accommodate the additional positions and altered footprint.
Q: What are the critical parameters for substitution compatibility?
A: The following parameters must match or exceed the original specification: pitch (0.100" / 2.54mm), contact type (male pin), mounting method (through hole), termination (solder), and flammability rating (UL94 V-0). Current rating and operating temperature range must meet or exceed application requirements.
Q: Why is the 4-103327-0 listed as obsolete?
A: Obsolete status indicates the part is no longer in active production. This affects long-term availability and may impact supply chain planning for production applications.
Q: Are there electrical compatibility concerns between these parts?
A: Both parts support the required current rating and operating temperature range for the 929834-01-29 application. The 4-103327-0 exceeds both specifications, providing electrical margin. Compatibility is determined by mechanical fit and PCB layout, not electrical performance.
Q: What packaging format is available for both parts?
A: Both the 929834-01-29 and 4-103327-0 are supplied in bulk packaging.
