TE Connectivity Erni 114437 ERMSH B Equivalent & Substitute Parts

Part Overview

The TE Connectivity Erni 114437 (ERMSH B) is an uncategorized connector component with an obsolete product status. As this part is no longer in active production, identifying functionally equivalent substitute components is essential for system redesign, maintenance, and procurement continuity. The original part maintains an inventory of 1118 pieces in new original stock; however, obsolescence requires evaluation of active alternative solutions that maintain compatibility with existing system requirements.

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity Erni 114437 have been identified based on the following substitution criteria:

Primary Substitution Logic:

• Connector Category: Backplane Connectors (active product category)
• Connector Type: Shroud for Male Pins
• Mounting Technology: Through Hole
• Pitch Standard: 0.079" (2.00mm) Hard Metric
• Product Status: Active (currently manufactured and supported)
• Compliance: RoHS and ECCN compliance verification

The identified substitutes represent active connector solutions within the backplane connector category that maintain hard metric pitch specifications and through-hole mounting compatibility. These parts are selected based on their active production status and current availability, contrasting with the obsolete status of the original component.

Engineering Selection Recommendations

TE Connectivity 646479-2 (CONN SHROUD HARD METRIC 175P GRY)

This substitute represents an active TE Connectivity backplane connector solution with 175-position capacity, 5+2 row configuration, and hard metric Type B specification. The part maintains ROHS3 compliance and EAR99 ECCN classification. Through-hole mounting and 0.079" (2.00mm) pitch alignment support direct mechanical integration. Moisture Sensitivity Level 1 (Unlimited) indicates no moisture-related handling restrictions. Current inventory of 743 pieces supports procurement requirements.

3M CP2-HSB125-4 (CONN SHROUD 125POS PCB)

This substitute provides an alternative backplane connector solution from 3M within the MetPak™ CP2 series, featuring 125-position capacity and 5-row configuration. The part maintains RoHS compliance and EAR99 ECCN classification. Through-hole mounting and 0.079" (2.00mm) pitch alignment support mechanical compatibility. Moisture Sensitivity Level classification as Not Applicable indicates standard handling procedures. Current inventory of 724 pieces supports procurement requirements.

Both substitutes are active products with established supply chains, current compliance certifications, and documented technical specifications suitable for backplane connector applications requiring hard metric pitch standards and through-hole mounting technology.

Frequently Asked Questions (FAQ)

Q: Why is the TE Connectivity Erni 114437 classified as obsolete?

A: The part has reached end-of-life status in the manufacturer's product portfolio. Obsolete classification indicates the component is no longer manufactured or supported by TE Connectivity Erni, necessitating alternative component selection for new designs and ongoing system support.

Q: What are the primary compatibility criteria for substituting the 114437?

A: Substitute parts must maintain alignment on connector category (backplane connectors), connector type (shroud for male pins), mounting technology (through-hole), and pitch specification (0.079" / 2.00mm hard metric). Product status should be active with current manufacturing support and compliance certifications.

Q: How do the TE Connectivity 646479-2 and 3M CP2-HSB125-4 differ?

A: The TE Connectivity 646479-2 provides 175-position capacity with 5+2 row configuration and gray color specification. The 3M CP2-HSB125-4 provides 125-position capacity with 5-row configuration. Both maintain 0.079" (2.00mm) pitch and through-hole mounting. Position count and row configuration differences require verification against specific application requirements.

Q: Are both substitute parts RoHS compliant?

A: Yes. The TE Connectivity 646479-2 maintains ROHS3 compliance. The 3M CP2-HSB125-4 maintains RoHS compliance. Both parts satisfy current environmental and regulatory requirements for electronic component procurement.

Q: What is the significance of Moisture Sensitivity Level (MSL) classification?

A: The TE Connectivity 646479-2 carries MSL 1 (Unlimited), indicating no moisture-related storage or handling restrictions. The 3M CP2-HSB125-4 carries MSL Not Applicable, indicating standard handling procedures. Both classifications support standard warehouse and assembly environments without specialized moisture control requirements.

Q: Do these substitutes include contacts?

A: No. Both substitute parts are specified as shroud components with contacts not included. Contact procurement must be evaluated separately based on application requirements and connector pin specifications.

Q: What ECCN classification applies to these substitutes?

A: Both substitute parts carry EAR99 ECCN classification, indicating standard commercial electronic components without specific export control restrictions beyond general commercial regulations.
