Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 213854-1 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following categories:

Electrical Parameters: Voltage rating (250VAC/DC), contact material (brass), contact finish (gold), and contact finish thickness (30.0µin / 0.76µm) must be identical to ensure proper signal integrity and mating performance.

Mechanical Parameters: The connector must retain the same number of positions (37), shell size insert designation (23-37), mounting configuration (panel mount, through hole with flange), fastening method (threaded), and orientation (B) to ensure physical compatibility with existing PCB layouts and enclosure designs.

Material and Environmental Parameters: Shell material (polyamide/nylon), flammability rating (UL94 V-0), and operating temperature range (-55°C to 105°C) must remain constant to maintain compliance with system environmental and safety requirements.

Termination Method: Solder termination is a critical parameter that must be preserved for compatibility with existing assembly processes and PCB designs.

The substitute part 213854-3 meets all these criteria while offering the advantage of active product status and improved compliance posture.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 213854-3 is the direct functional equivalent of the 213854-1 and serves as the primary substitute for this obsolete connector. Both parts share identical electrical and mechanical specifications, ensuring complete interchangeability in circuit design and PCB layout.

The 213854-3 offers significant advantages for new designs and component replenishment:

Product Status: The 213854-3 maintains active product status, ensuring ongoing availability and manufacturer support. The 213854-1 is obsolete and subject to supply discontinuation.

Compliance Posture: The 213854-3 is RoHS compliant, meeting current environmental regulations for electronic components. The 213854-1 is RoHS non-compliant, which may present regulatory challenges in certain applications and markets.

Inventory and Availability: The 213854-3 is available in higher quantities (1125 pieces in stock) compared to the 213854-1 (736 pieces), providing greater supply security for production and maintenance requirements.

Packaging: The 213854-3 is supplied in tray packaging, which is standard for production environments and facilitates automated assembly processes.

For applications currently using the 213854-1, direct substitution with the 213854-3 is supported without design modifications. The identical electrical and mechanical parameters ensure that existing solder connections, panel mounting configurations, and threaded fastening arrangements remain fully compatible.

Frequently Asked Questions (FAQ)

Q: Can the 213854-3 be used as a direct replacement for the 213854-1 in existing designs?

A: Yes. The 213854-3 is electrically and mechanically identical to the 213854-1. All critical parameters including connector type, position count, shell size, mounting configuration, termination method, voltage rating, operating temperature range, and contact specifications are identical. Direct substitution requires no design modifications.

Q: What are the key differences between the 213854-1 and 213854-3?

A: The primary differences are product status, compliance certification, and packaging. The 213854-3 is an active product with RoHS compliance and tray packaging, while the 213854-1 is obsolete, RoHS non-compliant, and supplied without specified packaging. All functional and electrical specifications are identical.

Q: Why is the 213854-1 listed as obsolete?

A: Obsolete status indicates that the manufacturer has discontinued active production of this part number. The 213854-3 represents the current production equivalent within the CPC Series 1 family.

Q: Are there any compatibility concerns when substituting the 213854-3 for the 213854-1?

A: No compatibility concerns exist. The identical shell size (23-37), mounting type (panel mount, through hole), fastening method (threaded), and orientation (B) ensure that the 213854-3 will fit existing PCB layouts and enclosure designs without modification. Solder termination compatibility is maintained.

Q: Does the RoHS compliance difference affect electrical performance?

A: RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both parts maintain identical electrical specifications including voltage rating (250VAC/DC), contact material (brass), contact finish (gold), and operating temperature range (-55°C to 105°C).

Q: What is the significance of the 30.0µin (0.76µm) contact finish thickness specification?

A: This specification defines the gold plating thickness on the brass contacts. Both the 213854-1 and 213854-3 maintain this identical thickness, ensuring consistent contact resistance, durability, and mating performance across connector cycles.

Q: Can the 213854-3 be used in applications originally designed for the 213854-1?

A: Yes. The 213854-3 is fully compatible with all applications designed for the 213854-1. The identical 37-position configuration, solder termination, threaded fastening, and environmental ratings (UL94 V-0, -55°C to 105°C operating range) ensure functional equivalence in all application contexts.

Q: What is the significance of MSL Level 1 (Unlimited) for both parts?

A: MSL Level 1 indicates that the connector has unlimited shelf life and requires no special moisture control during storage or handling. Both the 213854-1 and 213854-3 share this specification, simplifying inventory management and component procurement.
