Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ICO-308-ZLGT is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Number of positions: 8 (2 x 4) configuration
• Socket type: DIP with 0.3" (7.62mm) row spacing
• Mating pitch: 0.100" (2.54mm)
• Mating contact finish: Gold plating
• Mating contact material: Beryllium Copper
• Mounting configuration: Through Hole with solder termination
• Operating temperature range: -55°C ~ 125°C minimum
• RoHS compliance: ROHS3 Compliant

The substitute part 110-13-308-41-001000 (Mill-Max Manufacturing Corp.) satisfies all critical parameters, enabling direct functional equivalence in DIP socket applications.

Engineering Selection Recommendations

Primary Selection: ICO-308-ZLGT

The ICO-308-ZLGT remains the primary component choice when Samtec Inc. supply chain continuity is prioritized. Active product status and 939 units in current inventory support immediate availability for production requirements.

Substitute Selection: 110-13-308-41-001000

The 110-13-308-41-001000 (Mill-Max Manufacturing Corp.) functions as a direct electrical and mechanical equivalent. All critical socket parameters—position count, pitch, contact materials, mating finish, and operating temperature range—are identical. Both components maintain ROHS3 compliance and EAR99 export classification.

Differentiation Factors:

The substitute part exhibits a higher current rating (3 A versus 1 A) and gold-plated post contacts (versus tin-plated posts on the primary part). These characteristics represent performance enhancements rather than incompatibilities. The substitute part demonstrates greater inventory availability (3510 units) and includes specified termination post length (0.125" / 3.18mm).

Selection Basis:

Component selection between ICO-308-ZLGT and 110-13-308-41-001000 depends on supply chain requirements, inventory status, and lead time constraints. Both parts satisfy identical functional requirements for 8-position DIP socket applications with 0.3" row spacing and through-hole solder termination.

Frequently Asked Questions (FAQ)

Q: Can the 110-13-308-41-001000 directly replace the ICO-308-ZLGT in existing designs?

A: Yes. Both sockets maintain identical electrical and mechanical specifications for DIP package accommodation. The 8-position configuration, 0.100" pitch, gold-plated mating contacts, beryllium copper contact material, and -55°C to 125°C operating range are equivalent across both parts.

Q: What is the significance of the different current ratings (1 A vs. 3 A)?

A: The current rating specifies maximum continuous current per contact. The 110-13-308-41-001000 rating of 3 A exceeds the ICO-308-ZLGT specification of 1 A. For applications requiring currents below 1 A, both parts are functionally equivalent. Applications approaching or exceeding 1 A benefit from the higher-rated substitute part.

Q: Why do the post contact finishes differ (Tin vs. Gold)?

A: Post contact finish does not affect DIP package compatibility. The tin-plated posts on the ICO-308-ZLGT and gold-plated posts on the 110-13-308-41-001000 both provide solder termination capability. Gold plating on the substitute part offers enhanced corrosion resistance during storage and handling.

Q: Are both parts RoHS compliant?

A: Yes. Both the ICO-308-ZLGT and 110-13-308-41-001000 maintain ROHS3 compliance, satisfying regulatory requirements for restricted substance elimination.

Q: What determines socket substitutability for DIP packages?

A: Socket substitutability is determined by position count, row spacing, mating pitch, contact material, contact finish, mounting type, and operating temperature range. The ICO-308-ZLGT and 110-13-308-41-001000 are equivalent across all these parameters.

Q: Can these sockets accommodate different DIP package sizes?

A: No. Both sockets are configured for 8-position DIP packages with 0.3" (7.62mm) row spacing and 0.100" (2.54mm) pitch. Package compatibility is fixed by socket design and cannot be altered.

Q: What is the significance of the Moisture Sensitivity Level (MSL) rating on the substitute part?

A: The 110-13-308-41-001000 specifies MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. This specification is not provided for the ICO-308-ZLGT but does not affect functional equivalence.
