TE Connectivity 213856-1 Circular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 213856-1 is a 37-position circular connector receptacle with female sockets, designed for panel mount through-hole applications with solder termination. This connector features gold-plated brass contacts, polyamide shell construction, and operates across a temperature range of -55°C to 105°C with a voltage rating of 250VAC/DC.

The 213856-1 carries an obsolete product status, which necessitates identification of functionally equivalent alternatives for ongoing procurement and system maintenance. Active substitute components maintain identical electrical and mechanical specifications while offering current manufacturing availability and updated compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 213856-1 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute component must maintain identical specifications in the following categories:

Electrical Parameters: Connector type (receptacle, female sockets), number of positions (37), contact material (brass), contact finish (gold), contact finish thickness (30.0µin), voltage rating (250VAC/DC), and shielding configuration (unshielded).

Mechanical Parameters: Shell size - insert (23-37), mounting type (panel mount, through hole), mounting feature (flange), termination method (solder), fastening type (threaded), shell material (polyamide/nylon), and orientation (B).

Environmental Parameters: Operating temperature range (-55°C to 105°C), flammability rating (UL94 V-0), and moisture sensitivity level (1 - Unlimited).

The TE Connectivity 213856-4 satisfies all substitution criteria as a functionally equivalent component within the CPC series family, with the primary distinction being active product status and updated compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 213856-4 is the direct functional equivalent for the obsolete 213856-1 circular connector receptacle. Both components share identical electrical and mechanical specifications across all critical parameters including connector type, position count, shell size, mounting configuration, termination method, contact materials, and environmental ratings.

The 213856-4 provides the following advantages for component selection:

Product Status: The 213856-4 maintains active product status with current manufacturing support, ensuring long-term availability and supply chain continuity compared to the obsolete 213856-1.

Regulatory Compliance: The 213856-4 is ROHS3 compliant and carries REACH Unaffected status, meeting current regulatory requirements. The 213856-1 is RoHS non-compliant with undefined REACH status.

Functional Compatibility: All electrical and mechanical parameters remain identical, enabling direct substitution without circuit redesign or mechanical modification.

Packaging Consideration: The 213856-4 is supplied in tray packaging, whereas the 213856-1 is supplied in bulk packaging. Packaging format does not affect electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the 213856-4 be used as a direct replacement for the 213856-1 in existing applications?

A: Yes. The 213856-4 is electrically and mechanically identical to the 213856-1 across all specified parameters. Both components are 37-position circular connector receptacles with identical contact materials, finishes, voltage ratings, temperature ranges, and mounting configurations. Direct substitution is supported without modification.

Q: What is the difference between the 213856-1 and 213856-4?

A: The primary differences are product status and compliance certifications. The 213856-1 is obsolete with RoHS non-compliant status, while the 213856-4 is an active product with ROHS3 compliance and defined REACH status. Packaging differs (bulk versus tray), but electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns when substituting the 213856-4 for the 213856-1?

A: No compatibility concerns exist. Both connectors share identical shell size (23-37), mounting type (panel mount, through hole), fastening type (threaded), and all electrical parameters. The connectors are mechanically and electrically interchangeable.

Q: Does the packaging difference between bulk and tray affect connector performance?

A: No. Packaging format (bulk versus tray) is a logistics and handling consideration only. It does not affect electrical performance, mechanical fit, or environmental ratings of the connector.

Q: What is the voltage and temperature rating for these connectors?

A: Both the 213856-1 and 213856-4 are rated for 250VAC/DC operation across a temperature range of -55°C to 105°C. Both achieve UL94 V-0 flammability rating.

Q: Are these connectors shielded?

A: No. Both the 213856-1 and 213856-4 are unshielded circular connectors. If shielding is required for an application, alternative connector designs must be evaluated.

Q: What contact material and finish are used in these connectors?

A: Both connectors feature brass contacts with gold plating. The gold contact finish thickness is 30.0µin (0.76µm) on the mating surface, providing corrosion resistance and reliable electrical contact.

Q: Is the 213856-4 suitable for new designs?

A: Yes. The 213856-4 is an active product with current manufacturing support and ROHS3 compliance, making it suitable for new design implementations. The 213856-1 should not be used in new designs due to obsolete status.
