IL-Z-3PL-SMTYE-R1500 Equivalent & Substitute Parts

Part Overview

The IL-Z-3PL-SMTYE-R1500 is a surface mount, right-angle rectangular connector header manufactured by JAE Electronics. This 3-position, 1.25mm pitch connector is designed for board-to-cable/wire applications with shrouded 4-wall construction and solder termination. The product is currently obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support, maintenance, and production continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the IL-Z-3PL-SMTYE-R1500 is determined by strict alignment of the following critical parameters:

Connector Type & Contact Configuration: Header with male pins
Pitch & Position Count: 0.049" (1.25mm) pitch, 3-position, single-row configuration
Mounting & Orientation: Surface mount, right-angle orientation
Shrouding & Mechanical Form Factor: Shrouded 4-wall construction
Termination Method: Solder termination
Electrical Ratings: Current and voltage capacity must meet or exceed application requirements
Environmental Compliance: UL94 V-0 flammability rating and MSL classification

The substitute part 1734261-3 (TE Connectivity AMP Connectors) meets these core substitution criteria across all mechanical and electrical parameters specified in the input data.

Engineering Selection Recommendations

The 1734261-3 (TE Connectivity AMP Connectors) is a direct mechanical and functional equivalent to the IL-Z-3PL-SMTYE-R1500. Both connectors share identical pitch, position count, mounting orientation, shrouding configuration, and termination method.

Product Status Consideration: The IL-Z-3PL-SMTYE-R1500 is obsolete, while the 1734261-3 carries a Last Time Buy status. This indicates the TE Connectivity part remains available through authorized distributors but with limited future procurement windows.

Compliance & Certification: Both parts meet UL94 V-0 flammability requirements and carry MSL 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent environmental performance in standard applications.

Electrical Rating Variance: The substitute part is rated for 100VAC, which is lower than the original part's 200V rating. Applications requiring the full 200V rating must evaluate whether the substitute's voltage specification is acceptable for the intended circuit.

Inventory Availability: The substitute part (2100 pcs in stock) offers greater immediate availability compared to the original part (1107 pcs in stock).

Frequently Asked Questions (FAQ)

Q: Can the 1734261-3 be used as a direct replacement for the IL-Z-3PL-SMTYE-R1500?

A: Yes, from a mechanical and mating perspective. Both connectors have identical 1.25mm pitch, 3-position configuration, surface mount right-angle orientation, and shrouded 4-wall construction. Electrical compatibility depends on your application's voltage requirements, as the substitute is rated for 100VAC versus the original's 200V.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is based on connector type (header), contact configuration (male pins), pitch (1.25mm), position count (3), mounting method (surface mount right-angle), shrouding (4-wall), termination (solder), and electrical ratings (current and voltage). All these parameters must align between the original and substitute part.

Q: Does the substitute part have different packaging?

A: Yes. The 1734261-3 is supplied in Cut Tape (CT) packaging, while the original part's packaging specification was not provided in the input data. Verify that Cut Tape packaging is compatible with your assembly process.

Q: Are there compliance or certification differences?

A: Both parts carry UL94 V-0 flammability ratings and MSL 1 (Unlimited) moisture sensitivity levels. The substitute part is RoHS3 compliant; the original part's RoHS status was not specified in the input data.

Q: What is the difference in operating temperature range?

A: The original part operates from -40°C to 70°C, while the substitute operates from -25°C to 85°C. The substitute has a wider upper temperature limit but a narrower lower limit. Select based on your application's thermal requirements.

Q: Why is the voltage rating different?

A: The substitute part (1734261-3) is rated for 100VAC, while the original is rated for 200V. This difference reflects the design specifications of each manufacturer's product line. Confirm that your application's voltage requirements are compatible with the 100VAC rating before substitution.
