Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IL-Z-11PL-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: Current and voltage capacity sufficient for application requirements
• Material Compliance: UL94 V-0 flammability rating

The DF13A-11P-1.25H(21) manufactured by Hirose Electric Co Ltd meets these core substitution criteria across all critical dimensions and electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

The DF13A-11P-1.25H(21) is a direct functional substitute for the obsolete IL-Z-11PL-SMTYE. Both connectors share identical core specifications: 11-position headers at 1.25mm pitch with surface mount right-angle mounting, shrouded 4-wall construction, and solder termination.

Key considerations for selection:

Voltage Rating Differential: The IL-Z-11PL-SMTYE is rated at 200V while the DF13A-11P-1.25H(21) is rated at 150V. Applications requiring voltages above 150V must retain the original part or identify alternative substitutes with higher voltage ratings.

Operating Temperature Range: The DF13A-11P-1.25H(21) supports an extended operating temperature range (-35°C ~ 85°C) compared to the IL-Z-11PL-SMTYE (-40°C ~ 70°C), providing broader thermal compatibility for demanding environments.

Insulation Material: The IL-Z-11PL-SMTYE uses Polyphenylene Sulfide (PPS) while the DF13A-11P-1.25H(21) uses Polyamide (PA) Nylon. Both materials meet UL94 V-0 flammability requirements. Material selection should align with specific application chemical resistance and thermal requirements.

Fastening Mechanism: The IL-Z-11PL-SMTYE employs push-pull fastening while the DF13A-11P-1.25H(21) uses detent lock fastening. This difference affects mating/unmating force characteristics and should be evaluated for user interface requirements.

Product Status & Availability: The DF13A-11P-1.25H(21) maintains active production status with 2201 units in stock, ensuring long-term procurement availability compared to the obsolete IL-Z-11PL-SMTYE.

Compliance: Both connectors meet UL94 V-0 flammability standards. The DF13A-11P-1.25H(21) carries RoHS compliance certification.

Frequently Asked Questions (FAQ)

Q: Can the DF13A-11P-1.25H(21) directly replace the IL-Z-11PL-SMTYE in all applications?

A: Direct replacement is possible for applications operating at or below 150V. Applications requiring the 200V rating of the IL-Z-11PL-SMTYE require alternative substitutes or retention of the original part. Both connectors share identical pitch, position count, mounting type, and shrouding, ensuring mechanical and electrical compatibility within voltage constraints.

Q: What is the significance of the different fastening types (push-pull vs. detent lock)?

A: Push-pull fastening (IL-Z-11PL-SMTYE) and detent lock fastening (DF13A-11P-1.25H(21)) differ in mating/unmating force and engagement mechanism. Push-pull connectors typically require less force for disconnection, while detent lock connectors provide positive engagement confirmation. Selection depends on application requirements for connection security and user interface expectations.

Q: Are there compatibility concerns with the different insulation materials?

A: Both Polyphenylene Sulfide (PPS) and Polyamide (PA) Nylon meet UL94 V-0 flammability requirements. Material selection should consider application-specific chemical exposure, thermal cycling, and mechanical stress. PPS generally offers superior chemical resistance and higher continuous operating temperature capability, while PA Nylon provides cost efficiency and adequate performance for standard industrial applications.

Q: Does the extended operating temperature range of the DF13A-11P-1.25H(21) affect compatibility?

A: The DF13A-11P-1.25H(21) supports -35°C ~ 85°C compared to the IL-Z-11PL-SMTYE's -40°C ~ 70°C. For applications operating within the IL-Z-11PL-SMTYE's original range, the DF13A-11P-1.25H(21) provides equivalent or superior performance. Applications requiring operation below -35°C or above 85°C must evaluate specific thermal requirements against connector specifications.

Q: What packaging considerations apply to the DF13A-11P-1.25H(21)?

A: The DF13A-11P-1.25H(21) is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. Verify that existing assembly equipment and procedures accommodate this packaging format.

Q: Is RoHS compliance a factor in selecting the DF13A-11P-1.25H(21)?

A: The DF13A-11P-1.25H(21) carries RoHS compliance certification, meeting regulatory requirements for restricted hazardous substances in electrical and electronic equipment. Applications subject to RoHS regulations benefit from this certification. The IL-Z-11PL-SMTYE's RoHS status is not specified in available documentation.
