TE Connectivity 194234-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 194234-1 is a rectangular connector header designed for through-hole mounting applications. This vertical 4-position connector operates at 0.250" (6.35mm) pitch and is part of the Universal MATE-N-LOK II series. The connector features shrouded 4-wall construction with male pin contacts and solder termination, suitable for board-to-board or cable interconnection in general-purpose applications. The part maintains active product status and is RoHS compliant with unlimited moisture sensitivity rating. Substitute parts are identified when inventory constraints, series compatibility requirements, or specific performance characteristics necessitate alternative component selection while maintaining functional equivalence.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector headers is determined by strict alignment of core electrical and mechanical parameters. The primary substitute identified for TE Connectivity 194234-1 is part number 1586963-1, also manufactured by TE Connectivity AMP Connectors.

Substitution is valid when the following parameters match or are compatible:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (4)
• Mating pitch (0.250" / 6.35mm)
• Mounting method (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Voltage rating (600VAC minimum)
• Style (Board to Board or Cable)
• Fastening type (Locking Ramp)
• Insulation material (Polyamide/Nylon)

The substitute part 1586963-1 satisfies all core substitution criteria. Differences exist in series designation (MATE-N-LOK versus MATE-N-LOK II), contact material composition, contact finish specification, and operating temperature lower bound. These differences do not preclude functional substitution in applications where the substitute's specifications remain within system requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 194234-1 and 1586963-1 maintain active product status and RoHS compliance, qualifying both for current design implementations. Selection between these parts is determined by specific application requirements and environmental constraints.

The 194234-1 operates across an extended temperature range of -55°C to 105°C and features a UL94 V-0 flammability rating with silver-plated contacts on copper alloy base material. This configuration is appropriate for applications requiring superior low-temperature performance and enhanced flame resistance.

The 1586963-1 operates within a -40°C to 105°C temperature range with UL94 V-2 flammability rating and tin-plated phosphor bronze contacts. This part includes a specified current rating of 12A and glow wire compliance certification. The substitute is suitable for applications where the narrower temperature range is acceptable and where the specified current rating aligns with system requirements.

Both connectors share identical mating pitch, position count, mounting methodology, and voltage rating. The contact post length differs by 0.010" (0.26mm), which may impact PCB layout considerations. Series compatibility should be verified for applications requiring interchangeability with existing connector receptacles.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 194234-1 and 1586963-1 be used interchangeably in the same application?

A: Interchangeability depends on specific application requirements. Both parts share identical mating pitch (0.250"), position count (4), mounting type (through-hole), and voltage rating (600VAC). However, they belong to different series (MATE-N-LOK II versus MATE-N-LOK), which may affect compatibility with existing receptacle connectors. Verify that the mating receptacle is compatible with the selected header series before substitution.

Q: What are the key differences between these two parts?

A: The primary differences are: operating temperature range (194234-1: -55°C to 105°C; 1586963-1: -40°C to 105°C), flammability rating (194234-1: UL94 V-0; 1586963-1: UL94 V-2), contact material (194234-1: copper alloy with silver plating; 1586963-1: phosphor bronze with tin plating), contact post length (194234-1: 0.145"; 1586963-1: 0.155"), and current rating specification (1586963-1 specifies 12A; 194234-1 does not specify current rating).

Q: Which part should be selected for low-temperature applications?

A: The TE Connectivity 194234-1 is specified for operation down to -55°C, making it suitable for applications requiring extended low-temperature performance. The 1586963-1 is rated to -40°C minimum, which may be insufficient for applications requiring operation below this threshold.

Q: Are both parts RoHS compliant?

A: Yes, both TE Connectivity 194234-1 and 1586963-1 are RoHS compliant with unlimited moisture sensitivity level (MSL 1).

Q: What is the significance of the contact post length difference?

A: The contact post length differs by 0.010" (0.26mm), with 194234-1 at 0.145" and 1586963-1 at 0.155". This difference may affect solder joint formation and PCB pad design. Verify that PCB through-hole depth and pad specifications accommodate the selected part's contact post length.

Q: Does the flammability rating difference impact substitution decisions?

A: The flammability rating difference (UL94 V-0 versus UL94 V-2) may be significant for applications subject to specific safety standards or industry regulations. Applications requiring UL94 V-0 certification must use the 194234-1. Applications with UL94 V-2 requirements can use either part.

Q: Is the 12A current rating of 1586963-1 a limiting factor?

A: The 1586963-1 specifies a 12A current rating. Applications requiring current capacity above 12A per contact should not use this part. The 194234-1 does not specify a current rating in the provided data; verify system current requirements against available specifications before selection.
