• Pitch: 0.079" (2.00mm)
• Number of Rows: 4
• Mounting Type: Through Hole
• Termination: Press-Fit
• Connector Type: Header, Male Pins
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Compatibility Factors:

• Operating Temperature Range: -55°C ~ 125°C
• Contact Finish: Gold
• Category: Backplane Connectors

The identified substitute parts meet these core electrical and mechanical parameters, enabling direct functional replacement in applications previously specified for the 536504-8. Both substitute parts are classified as active products, ensuring ongoing availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

For 70453-1304 (Amphenol ICC Metral® High Speed):

This substitute part maintains full compatibility with the primary electrical and mechanical specifications of the 536504-8. The 70453-1304 is an active product with confirmed current availability, eliminating obsolescence concerns. Both parts share identical pitch (0.079"), position count (144), row configuration (4), mounting methodology (through-hole), and termination approach (press-fit). The operating temperature range (-55°C to 125°C) and flammability rating (UL94 V-0) are equivalent. The 70453-1304 provides specified current rating (1.5A) and contact finish thickness (30.0µin), offering enhanced technical documentation compared to the original part.

For 70463-5026 (Amphenol ICC Metral® MONOBLOCK):

This substitute part satisfies the core mechanical and electrical parameters required for functional equivalence. The 70463-5026 is an active product with confirmed availability. Pitch, row configuration, mounting type, and termination method are identical to the 536504-8. The MONOBLOCK connector style and male pins with blades configuration represent a structural variation. The number of positions loaded (17) differs from the main part specification (all positions loaded), indicating a partial-load configuration. Contact finish includes GXT™ technology with increased thickness (50.0µin), providing enhanced durability characteristics. Operating temperature and voltage rating specifications are not provided for this part.

Both substitute parts comply with identical regulatory classifications (EAR99, HTSUS 8536.69.4040, RoHS non-compliant, MSL 1) and share the same flammability rating (UL94 V-0).

Frequently Asked Questions (FAQ)

Q: What makes 70453-1304 and 70463-5026 suitable substitutes for the obsolete 536504-8?

A: Both parts match the critical mechanical and electrical parameters: 144 positions, 0.079" (2.00mm) pitch, 4-row configuration, through-hole mounting, and press-fit termination. All three parts share UL94 V-0 flammability rating, MSL 1 moisture sensitivity, and identical regulatory classifications. The substitute parts are active products, ensuring supply continuity.

Q: What is the primary difference between the two substitute options?

A: The 70453-1304 features a High Speed connector style with all 144 positions loaded, matching the original part's full-load configuration. The 70463-5026 uses a MONOBLOCK design with male pins and blades, with only 17 positions loaded. The 70463-5026 provides enhanced contact finish thickness (50.0µin with GXT™ technology) compared to the 70453-1304 (30.0µin).

Q: Are there any compliance or regulatory differences between the main part and substitutes?

A: All three parts share identical regulatory status: RoHS non-compliant, EAR99 classification, HTSUS code 8536.69.4040, and MSL 1. No compliance barriers exist for substitution.

Q: What operating temperature range should be considered for the 70463-5026?

A: The operating temperature specification for 70463-5026 is not provided in the technical documentation. The 70453-1304 maintains the original -55°C to 125°C range. Verify temperature requirements with application specifications before selecting the 70463-5026.

Q: How do the packaging formats differ?

A: The original 536504-8 packaging is not specified. Both substitute parts are supplied in tube packaging, which is standard for backplane connector headers and suitable for automated assembly processes.

Q: Is the 70453-1304 current rating (1.5A) compatible with the original 536504-8 application?

A: The original 536504-8 does not specify a current rating. The 70453-1304 provides 1.5A rating. Verify that your application current requirements do not exceed 1.5A when selecting this substitute.

Q: What does the MONOBLOCK configuration in the 70463-5026 indicate?

A: MONOBLOCK refers to an integrated connector body design where the male pins and blades are formed as a single structural unit. This design provides enhanced mechanical stability and is suitable for high-density backplane applications. The partial-load configuration (17 of 144 positions) indicates selective position utilization.
