IL-Z-11PL1-SMTYE Equivalent & Substitute Parts

Part Overview

The IL-Z-11PL1-SMTYE is a rectangular connector header manufactured by JAE Electronics, designed for surface mount, right-angle applications with 11 positions at 1.25mm pitch. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing production support and design continuity. The connector features shrouded 4-wall construction with solder termination and friction lock fastening, suitable for board-to-cable/wire interconnections in applications requiring 1A per contact at 200V.

Substitute Part Grouping Explanation

Substitution eligibility for the IL-Z-11PL1-SMTYE is determined by strict alignment of the following critical parameters:

Connector Type & Contact Configuration: Header with male pins
Position Count & Pitch: 11 positions at 0.049" (1.25mm) mating pitch
Mounting & Orientation: Surface mount, right-angle configuration
Shrouding Design: Shrouded 4-wall construction
Termination Method: Solder termination
Electrical Ratings: Minimum 1A per contact and 125V voltage rating
Environmental Compliance: UL94 V-0 flammability rating and MSL 1 classification

The substitute part 10114830-11111LF meets these core substitution criteria. While minor variations exist in contact material (phosphor bronze vs. brass), insulation material (LCP vs. PPS), and fastening mechanism (detent lock vs. friction lock), these differences remain within acceptable tolerance for functional equivalence in board-to-cable/wire interconnection applications.

Engineering Selection Recommendations

The 10114830-11111LF from Amphenol ICC qualifies as a functional substitute for the obsolete IL-Z-11PL1-SMTYE. The substitute maintains active product status with confirmed RoHS compliance, providing supply chain continuity and regulatory alignment for new production runs.

Key considerations for selection:

Voltage Derating: The substitute operates at 125V maximum versus the original 200V rating. Applications operating below 125V present no constraint; designs requiring the full 200V rating require alternative evaluation.
Temperature Range: The substitute supports -40°C to 105°C, exceeding the original -40°C to 70°C range, providing enhanced thermal margin for demanding environments.
Fastening Mechanism: The detent lock on the substitute provides positive engagement compared to the friction lock on the original, potentially improving mating reliability in vibration-prone applications.
Insulation Material: LCP offers superior dimensional stability and chemical resistance compared to PPS, with both materials meeting UL94 V-0 flammability requirements.

Frequently Asked Questions (FAQ)

Q: Can the 10114830-11111LF directly replace the IL-Z-11PL1-SMTYE in existing designs?

A: Direct replacement is possible for applications operating at 125V or below. The 11-position, 1.25mm pitch, surface-mount right-angle configuration, and solder termination are identical. Designs requiring the original 200V rating require alternative component evaluation.

Q: What is the difference between friction lock and detent lock fastening?

A: Friction lock relies on contact pressure to maintain mating; detent lock uses a positive mechanical engagement feature. Detent lock typically provides more secure retention in high-vibration environments.

Q: Are the insulation materials interchangeable?

A: Both PPS (original) and LCP (substitute) meet UL94 V-0 flammability requirements. LCP offers superior dimensional stability and chemical resistance. Material selection should be verified against specific application chemical exposure requirements.

Q: Does the substitute meet RoHS compliance?

A: Yes, the 10114830-11111LF is RoHS Compliant. The original IL-Z-11PL1-SMTYE RoHS status is not specified in available documentation.

Q: What is the packaging difference?

A: The IL-Z-11PL1-SMTYE packaging is not specified. The 10114830-11111LF is supplied in Tape & Reel (TR) format, standard for surface-mount production environments.

Q: Are both connectors rated for 1A per contact?

A: Yes, both connectors are rated for 1A per contact, maintaining current-carrying capacity equivalence.
