TE Connectivity 6-146252-5 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 6-146252-5 is an AMPMODU Mod II rectangular connector header designed for through-hole mounting applications. This 30-position, 2-row male pin header operates at 0.100" (2.54mm) pitch and supports 3A current per contact. The connector features gold-plated mating contacts, tin-plated posts, and is constructed from copper alloy with liquid crystal polymer insulation. The part maintains active product status and is RoHS compliant with unlimited moisture sensitivity level rating.

Substitute parts are necessary when the primary part experiences extended lead times, inventory constraints, or when design requirements permit alternative connector geometries, contact materials, or operating temperature ranges within the same functional category.

Engineering Selection Recommendations

All listed substitute parts maintain active product status and RoHS compliance, meeting the core regulatory requirements of the TE Connectivity 6-146252-5.

Primary Substitutes (Highest Compatibility):

The Amphenol ICC 68691-130HLF and Samtec MTSW-115-08-S-D-310 present the closest dimensional and electrical alignment with the original part. Both maintain identical pitch, position count, row configuration, and current rating. The 68691-130HLF operates across an extended temperature range (-65°C to 130°C) and the MTSW-115-08-S-D-310 provides comparable contact geometry with gold-plated mating surfaces.

Secondary Substitutes (Acceptable with Design Verification):

The Harwin M20-9981545 and M20-9981546 series offer cuttable connector functionality with identical pitch and position specifications. These parts accommodate applications requiring custom connector lengths. The M20-9981545 features gold-plated mating contacts while the M20-9981546 provides tin-plated mating surfaces. Both operate within the -40°C to 105°C range, which encompasses the primary operating window of the original part.

The Hirose A1-30PA-2.54DSA(71) maintains full electrical compatibility but operates within a reduced temperature range (-55°C to 85°C). This part is suitable for applications not requiring the full -65°C lower temperature limit of the original specification.

Alternative Consideration:

The Samtec BBD-115-T-A features circular contact geometry and extended operating temperature range (-55°C to 125°C) but lacks published current rating and flammability specifications. This part requires design review for applications with strict electrical or safety certification requirements.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 68691-130HLF directly replace the TE Connectivity 6-146252-5 in existing PCB designs?

A: Yes. Both connectors share identical pitch (0.100"), position count (30), row configuration (2 rows), and row spacing (0.100"). The 68691-130HLF operates across an extended temperature range and maintains equivalent current rating (3A) and flammability rating (UL94 V-0). Physical footprint compatibility is confirmed.

Q: What is the primary difference between the Harwin M20-9981545 and M20-9981546?

A: The M20-9981545 features gold-plated mating contacts, while the M20-9981546 provides tin-plated mating contacts. Both parts share identical pitch, position count, row spacing, and current rating. Contact finish selection depends on application requirements for corrosion resistance and signal integrity.

Q: Are the Samtec MTSW-115-08-S-D-310 and MTSW-115-08-T-D-240 interchangeable?

A: Both parts share identical pitch, position count, and row configuration. The MTSW-115-08-S-D-310 features gold-plated mating contacts and operates from -55°C to 125°C. The MTSW-115-08-T-D-240 features tin-plated mating contacts and operates from -55°C to 105°C. Selection depends on temperature requirements and contact finish specifications for the application.

Q: Does the Hirose A1-30PA-2.54DSA(71) operate within the full temperature range of the original TE part?

A: No. The Hirose part operates from -55°C to 85°C, which does not encompass the -65°C lower limit of the TE Connectivity 6-146252-5. This part is suitable for applications operating within the -55°C to 85°C window only.

Q: What packaging formats are available for these substitute parts?

A: The TE Connectivity 6-146252-5 is supplied in bulk packaging. Substitute parts are available in multiple packaging formats: Amphenol ICC 68691-130HLF (bag), Hirose A1-30PA-2.54DSA(71) (tray), Samtec BBD-115-T-A (tube), Harwin M20 series (bulk), and Samtec MTSW series (bulk). Packaging selection does not affect electrical or mechanical compatibility.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts maintain RoHS compliance status. The TE Connectivity 6-146252-5 is RoHS Compliant, while all substitute parts are either RoHS Compliant or ROHS3 Compliant, meeting current regulatory requirements.

Q: Can the Samtec BBD-115-T-A be used in applications requiring UL94 V-0 certification?

A: The BBD-115-T-A does not provide published material flammability rating information. Applications with strict flammability certification requirements should select from parts with confirmed UL94 V-0 rating: Amphenol ICC 68691-130HLF, Hirose A1-30PA-2.54DSA(71), Harwin M20 series, or Samtec MTSW series.

Q: What is the significance of the "cuttable" designation on Harwin and Samtec parts?

A: The cuttable designation indicates that the connector header can be mechanically separated into individual or smaller position groups. This feature enables custom connector configurations from a single part. The TE Connectivity 6-146252-5 is designated as "breakaway," providing similar functionality. This feature does not affect electrical compatibility with standard 30-position applications.
