TE Connectivity ALCOSWITCH 1571626-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity ALCOSWITCH 1571626-3 is an active-status tactile switch designed for surface mount applications. This SPST-NO (Single Pole Single Throw - Normally Open) switch operates at 0.05A @ 12VDC and features a 2.50mm actuator height with top actuation. The switch is supplied in bulk packaging and is RoHS3 compliant with MSL 1 rating. Alternative part numbers are necessary when bulk packaging is unavailable or when tape and reel packaging is required for automated assembly processes.

Substitute Part Grouping Explanation

The substitute part FSM2JELGLTR is functionally equivalent to the main part 1571626-3 based on the following critical parameters:

• Circuit Configuration: Both parts are SPST-NO switches with identical electrical function (Off-Mom)
• Contact Rating: Both rated at 0.05A @ 12VDC
• Physical Dimensions: Both feature 6.20mm x 6.20mm outline with 2.50mm actuator height
• Actuator Specifications: Both use top-actuated standard actuators with 0.25mm switch travel and 100gf operating force
• Mechanical Performance: Both rated for 1,000,000 cycles mechanical life
• Operating Temperature: Both operate across -35°C ~ 85°C range
• Termination: Both use gull wing termination for surface mount assembly
• Environmental Compliance: Both are RoHS compliant and MSL 1 rated

The primary difference between these parts is packaging format: 1571626-3 is supplied in bulk, while FSM2JELGLTR is supplied in tape and reel format. Both parts share the same Extended Life series designation and active product status.

Parameter Comparison

Engineering Selection Recommendations

Both 1571626-3 and FSM2JELGLTR are active-status products from TE Connectivity ALCOSWITCH with identical electrical and mechanical specifications. Selection between these parts should be based on assembly requirements and supply chain considerations:

1571626-3 (Bulk Packaging): Select this part number for manual assembly operations, prototype builds, or applications where individual component handling is preferred. Bulk packaging provides flexibility for small-quantity orders.

FSM2JELGLTR (Tape & Reel Packaging): Select this part number for high-volume automated assembly processes. Tape and reel format is optimized for pick-and-place equipment and reduces handling labor in production environments.

Both parts maintain identical RoHS compliance status (RoHS3 for 1571626-3, RoHS Compliant for FSM2JELGLTR), MSL 1 rating, and export classification (EAR99). No functional or performance differences exist between these part numbers. The choice is determined solely by packaging format and assembly methodology.

Frequently Asked Questions (FAQ)

Q: Can FSM2JELGLTR be used as a direct replacement for 1571626-3 in existing designs?

A: Yes. FSM2JELGLTR is electrically and mechanically identical to 1571626-3. All critical parameters including circuit configuration, contact rating, actuator height, switch travel, mechanical life, and operating temperature range are identical. The only difference is packaging format (tape and reel versus bulk).

Q: What is the primary difference between these two part numbers?

A: The primary difference is packaging. 1571626-3 is supplied in bulk packaging, while FSM2JELGLTR is supplied in tape and reel format. This affects handling, storage, and assembly methodology but does not impact electrical or mechanical performance.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are RoHS compliant, MSL 1 rated, and classified as EAR99 for export purposes. Both share identical HTSUS classification (8536.50.9031). The RoHS designation differs slightly (RoHS3 Compliant versus RoHS Compliant), but both meet current regulatory requirements.

Q: Which part should be selected for automated assembly?

A: FSM2JELGLTR in tape and reel format is optimized for automated pick-and-place assembly equipment. Tape and reel packaging provides proper component spacing and orientation for high-speed production lines.

Q: Which part should be selected for manual assembly or prototyping?

A: 1571626-3 in bulk packaging is suitable for manual assembly, prototype development, and low-volume applications where individual component handling is standard practice.

Q: Are the actuator specifications identical between these parts?

A: Yes. Both parts feature standard top-actuated actuators with 2.50mm height, 0.25mm switch travel, and 100gf operating force. Actuator material is thermoplastic for both parts.

Q: Do these parts have identical mechanical life ratings?

A: Yes. Both 1571626-3 and FSM2JELGLTR are rated for 1,000,000 cycles mechanical life, indicating identical durability and reliability characteristics.

Q: What is the operating temperature range for both parts?

A: Both parts operate across an identical temperature range of -35°C to 85°C, making them suitable for industrial and commercial applications within this thermal envelope.

Q: Can inventory be mixed between these two part numbers in production?

A: Mixing is not recommended from a supply chain management perspective. While electrically and mechanically identical, maintaining separate part numbers ensures proper tracking, traceability, and assembly process control. Use 1571626-3 for bulk-packaged inventory and FSM2JELGLTR for tape and reel inventory according to assembly requirements.
