M30-6100746 Equivalent & Substitute Parts

Part Overview

The M30-6100746 is a rectangular connector header manufactured by Harwin Inc., featuring a vertical through-hole mount configuration with 7 positions at 1.25mm pitch. This shrouded 4-wall header is designed for board-to-cable/wire applications with solder termination and detent lock fastening. The part is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M30-6100746 is determined by the following critical parameters: connector type (header), contact type (male pin), mating pitch (1.25mm), mounting method (through hole), shrouding configuration (4-wall), termination method (solder), and fastening mechanism (detent lock). These parameters define the mechanical and electrical interface compatibility.

The substitute parts are grouped into two categories:

Direct Position Match (M30-6100846): Same manufacturer series with identical pitch, shrouding, mounting, and termination. Differs only in position count (8 vs. 7), making it suitable for applications where additional contact capacity is acceptable within the same footprint family.

Cross-Manufacturer Equivalent (10114829-11107LF): Amphenol ICC alternative with matching position count (7), pitch (1.25mm), shrouding (4-wall), mounting (through hole), and termination (solder). Maintains functional compatibility despite differences in contact material and finish specifications.

Engineering Selection Recommendations

M30-6100846 Selection: This Harwin Inc. part maintains full compatibility within the M30 series family. It is the preferred substitute when the application can accommodate an 8-position configuration. Active product status ensures long-term availability and supply chain stability. ROHS3 compliance aligns with the original part's environmental standards. Selection of this part eliminates cross-manufacturer integration concerns and maintains consistent supplier relationships.

10114829-11107LF Selection: This Amphenol ICC alternative provides exact position matching (7 positions) with the original M30-6100746. The part is active and RoHS compliant. The extended operating temperature range (-40°C to 105°C) exceeds the original specification, providing thermal margin for demanding applications. Gold plating on mating contacts and phosphor bronze material offer enhanced contact reliability compared to tin-plated brass. Insulation height variance (0.165" vs. 0.169") is within acceptable mechanical tolerance for standard PCB layouts. This part is suitable for applications requiring cross-manufacturer sourcing flexibility or enhanced environmental performance.

Frequently Asked Questions (FAQ)

Q: Can M30-6100846 directly replace M30-6100746 in existing designs?

A: M30-6100846 is mechanically and electrically compatible with M30-6100746 for all shared interface parameters. The 8-position configuration accommodates the original 7-position requirement. PCB footprint compatibility depends on whether the design includes provisions for the additional contact position. Connector mating compatibility is maintained through identical pitch, shrouding, and fastening specifications.

Q: What are the key differences between the Harwin and Amphenol alternatives?

A: M30-6100846 maintains identical material composition (brass contacts, tin finish, PA66 insulation) and operating temperature range as the original. 10114829-11107LF uses phosphor bronze contacts with gold plating and LCP insulation, providing enhanced contact durability and a wider operating temperature range (-40°C to 105°C). Both maintain 1.25mm pitch, 4-wall shrouding, and detent lock fastening. Contact material and finish differences do not affect mechanical mating compatibility.

Q: Are there packaging considerations when selecting a substitute?

A: M30-6100746 packaging is not specified in available data. M30-6100846 is supplied in tube packaging. 10114829-11107LF is supplied in tape and reel format. Packaging selection should align with assembly process requirements and volume considerations. Both substitute parts are available in quantities suitable for production implementation.

Q: Does the insulation height variance between M30-6100746 and 10114829-11107LF affect PCB compatibility?

A: The insulation height difference is 0.004" (0.10mm), representing a 2.3% variance. This falls within standard PCB design tolerances for through-hole component placement. Mating interface compatibility is unaffected, as the critical dimension is the contact post length (0.091" for all three parts), which is identical.

Q: Which substitute part should be selected for new designs?

A: For new designs within the Harwin ecosystem, M30-6100846 is recommended if the 8-position configuration is acceptable. For applications requiring exact 7-position matching or enhanced thermal performance, 10114829-11107LF provides equivalent functionality with superior contact reliability through gold plating and extended operating temperature range.
