Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 5338048-2 is based on the following critical parameters that must align across equivalent components:

Primary Matching Criteria:

• Circuit configuration: SPST
• Number of positions: 2
• Actuator type: Slide (Standard)
• Mounting type: Through Hole
• Pitch: 0.100" (2.54mm)
• Termination style: PC Pin

Secondary Compatibility Factors:

• Operating temperature range (substitute must cover or exceed the original range)
• Contact material and finish
• Body material composition
• RoHS and MSL compliance status

The E-Switch KAS1102E meets all primary matching criteria and provides enhanced specifications in several secondary parameters, including extended operating temperature range (-40°C to 85°C), active product status, and ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 5338048-2 (Original Part): The original part is obsolete and no longer in active production. While 904 pieces are currently in stock, this component should be considered for legacy system maintenance only. The part meets RoHS compliance and carries MSL 1 rating, suitable for standard storage conditions.

E-Switch KAS1102E (Substitute Part): The KAS1102E is the recommended substitute for new designs and ongoing procurement. This part is active in production with 1,056 pieces in stock. It maintains all critical functional parameters (SPST circuit, 2-position configuration, slide actuator, through-hole mounting, 0.100" pitch) while providing enhanced specifications:

• Extended operating temperature range (-40°C to 85°C versus -25°C to 70°C)
• ROHS3 compliance (versus RoHS compliant)
• Smaller physical footprint (0.275" height and 0.254" length versus 0.354" and 0.300")
• Specified electrical and mechanical life ratings (2,000 cycles)
• Gold contact finish (versus tin)
• Active product status ensuring long-term availability

The KAS1102E is suitable for direct substitution in applications where the original 5338048-2 was specified, provided that the reduced physical dimensions and enhanced temperature range do not conflict with existing board layout or thermal requirements.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch KAS1102E directly replace the TE Connectivity 5338048-2 in existing designs?

A: Yes, the KAS1102E provides direct functional substitution. Both components share identical circuit configuration (SPST), position count (2), actuator type (slide standard), mounting method (through hole), and pitch (0.100"). The KAS1102E features a smaller physical profile and extended operating temperature range, which are compatible with applications originally designed for the 5338048-2.

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

A: The primary differences are product status (obsolete versus active), physical dimensions (KAS1102E is more compact), operating temperature range (KAS1102E extends to -40°C and 85°C), contact finish (gold versus tin), and body material composition (PBT glass-filled versus PA nylon glass-filled). Both maintain the same electrical interface and mounting characteristics.

Q: Are there any compatibility concerns with PCB layout when substituting the KAS1102E?

A: The KAS1102E has a reduced height above board (0.275" versus 0.354") and shorter length (0.254" versus 0.300"). These dimensional reductions are generally favorable for board space optimization. However, verify that the reduced profile does not affect any mechanical clearances or component placement constraints in your specific application.

Q: What is the significance of the contact finish difference (tin versus gold)?

A: The KAS1102E uses gold contact finish, which provides superior corrosion resistance and lower contact resistance compared to the tin finish of the 5338048-2. This enhancement improves long-term reliability and signal integrity, particularly in environments with moisture or corrosive atmospheres.

Q: Are both parts RoHS compliant?

A: Yes. The TE Connectivity 5338048-2 is RoHS compliant, and the E-Switch KAS1102E is ROHS3 compliant. Both meet current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the MSL rating, and does it affect storage or handling?

A: Both components carry MSL 1 (Unlimited) rating, indicating they are not moisture-sensitive and require no special storage conditions or baking procedures prior to assembly. Standard warehouse storage conditions are appropriate for both parts.

Q: Does the KAS1102E have specified electrical and mechanical life ratings?

A: Yes, the KAS1102E specifies 2,000 cycles for both electrical and mechanical life. The original 5338048-2 does not provide these specifications in the available documentation. This rated cycle life provides a quantifiable reliability baseline for design calculations.

Q: What packaging format is available for the KAS1102E?

A: The KAS1102E is supplied in tube packaging, whereas the original part packaging format is not specified. Verify that tube packaging is compatible with your assembly and inventory management processes.
