Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SIL08M153J is determined by the following core parameters:

Primary Compatibility Criteria:

• Resistance value: 15k Ohm (exact match required)
• Number of resistors: 4 elements (exact match required)
• Circuit topology: Isolated configuration (exact match required)
• Package designation: 8-SIP (exact match required)
• Mounting technology: Through Hole (exact match required)
• Operating temperature range: -55°C to 125°C minimum (equal or broader range acceptable)
• Pin count: 8 pins (exact match required)

The substitute part 4608X-102-153LF manufactured by Bourns Inc. satisfies all primary compatibility criteria. This part maintains identical resistance, resistor count, circuit isolation, package type, mounting method, and pin configuration. Physical dimensions remain within acceptable tolerance for direct board-level substitution. Operating temperature range matches the specified -55°C to 125°C envelope.

Engineering Selection Recommendations

SIL08M153J Selection Criteria: The TE Connectivity SIL08M153J is appropriate for applications where RoHS non-compliance is acceptable and REACH-affected material status does not present regulatory constraints. This part provides baseline performance specifications with 200mW power per element and ±200ppm/°C temperature coefficient. Selection is suitable for cost-optimized designs where tolerance and thermal stability requirements align with ±5% and ±200ppm/°C specifications.

4608X-102-153LF Selection Criteria: The Bourns Inc. 4608X-102-153LF is appropriate for applications requiring ROHS3 compliance and REACH-unaffected material status. This substitute part delivers enhanced performance through tighter ±2% tolerance, increased 300mW power per element rating, and improved ±100ppm/°C temperature coefficient. Selection is suitable for applications demanding superior thermal stability, higher power dissipation capability, and regulatory compliance with RoHS3 and REACH directives. Both parts maintain identical electrical function and board-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 4608X-102-153LF directly replace the SIL08M153J on existing PCBs?

A: Yes. Both parts feature identical 8-SIP package configuration, 8-pin count, and through-hole mounting technology. Physical dimensions are compatible within standard PCB tolerance specifications (20.32mm vs. 20.27mm length; 2.50mm vs. 2.49mm width; 5.08mm seated height for both). Direct board-level substitution is supported without PCB redesign.

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

A: The 4608X-102-153LF provides three performance enhancements: tolerance specification improves from ±5% to ±2%, power per element increases from 200mW to 300mW, and temperature coefficient improves from ±200ppm/°C to ±100ppm/°C. Resistance value, circuit topology, and operating temperature range remain identical.

Q: Are there compliance or regulatory differences?

A: Yes. The SIL08M153J is RoHS non-compliant and REACH-affected. The 4608X-102-153LF is ROHS3 compliant and REACH-unaffected. Applications subject to RoHS3 or REACH regulatory requirements must use the Bourns substitute part.

Q: Do both parts operate across the same temperature range?

A: Yes. Both parts operate from -55°C to 125°C. However, the 4608X-102-153LF maintains superior temperature stability with ±100ppm/°C coefficient compared to the SIL08M153J at ±200ppm/°C.

Q: Is the higher power rating of the 4608X-102-153LF a requirement for substitution?

A: No. The higher 300mW power per element rating of the 4608X-102-153LF is a performance enhancement, not a substitution requirement. Applications designed for 200mW operation function correctly with the 300mW-rated substitute part.

Q: What is the significance of the tighter tolerance in the substitute part?

A: The 4608X-102-153LF tolerance of ±2% provides improved resistor value accuracy compared to the SIL08M153J at ±5%. Applications requiring tighter resistor matching or more precise circuit performance benefit from this enhanced specification.
